Figure 6

Real time systolic images (2–5) of the left ventricle from Fig. 1. Superimposed is a grid (red) that was deformed offline using the Gaussian transformation T applied on the image 1 according to the algorithm in Fig. 4. The grid (red) mimics the deformed tag lines in the underlying myocardial tissue. The estimated optimal α values are respectively 12, 16, 19 and 20.
